1.按姓氏笔画排序:
select * from tablename order by customername collate chinese_prc_stroke_ci_as
2.数据库加密:
select encrypt('原始密码')
select pwdencrypt('原始密码')
select pwdcompare('原始密码','加密后密码') = 1--相同；否则不相同 encrypt('原始密码')
select pwdencrypt('原始密码')
select pwdcompare('原始密码','加密后密码') = 1--相同；否则不相同
3.取回表中字段:
declare @list varchar(1000),@sql nvarchar(1000)
select @list=@list ',' b.name from sysobjects a,syscolumns b where a.id=b.id and a.name='表a'
set @sql='select ' right(@list,len(@list)-1) ' from 表a'
exec (@sql)
4.查看硬盘分区:
exec master..xp_fixeddrives
5.比较a,b表是否相等:
if (select checksum_agg(binary_checksum(*)) from a)
=
(select checksum_agg(binary_checksum(*)) from b)
print '相等'
else
print '不相等'
6.杀掉所有的事件探察器进程:
declare hcforeach cursor global for select 'kill ' rtrim(spid) from master.dbo.sysprocesses
where program_name in('sql profiler',n'sql 事件探查器')
exec sp_msforeach_worker '?'
'www.knowsky.com
7.记录搜索:
开头到n条记录
select top n * from 表
-------------------------------
n到m条记录(要有主索引id)
select top m-n * from 表 where id in (select top m id from 表) order by id desc
----------------------------------
n到结尾记录
select top n * from 表 order by id desc
8.如何修改数据库的名称:
sp_renamedb 'old_name', 'new_name'
9：获取当前数据库中的所有用户表
select name from sysobjects where xtype='u' and status>=0
10：获取某一个表的所有字段
select name from syscolumns where id=object_id('表名')
11：查看与某一个表相关的视图、存储过程、函数
select a.* from sysobjects a, syscomments b where a.id = b.id and b.text like '%表名%'
12：查看当前数据库中所有存储过程
select name as 存储过程名称 from sysobjects where xtype='p'
13：查询用户创建的所有数据库
